BBANCHIE, OI TOLEDO, OHIQ-ASSIGNOR TO SURFACE COMBUSTION CORI'OBA- TI OH, O1 TOLEDO, OHIO, A CORPORATION OF NEW YORK mwr RADIATOR Application filed December 18, 1831. Serial No. 581,984.

This invention relates to improvements in heat radiators of the gas-fired type, and has for its general object to provide a heat radiator of such form and construction as to obtain a relatively great heat radiating area in a compact construction. More particularly, it is an object of the invention to provide a heat radiator which shall consist of two main members of cast metal, the members being so combined that there shall be formed a plurality of heat radiating panels, one set of panels extending from one base and the other set of panels extending from another base, the two bases being so constructed as to form a common chamber from which the hot gases flow to the respective panels. .7 Referring to the drawing wherein the preferred form of the invention is shown,

Fig. 1 shows the improved radiator positioned within a casing containing a blower for forcing air over the radiator surfaces, the lower portion of the heat radiator being broken away to show the gas burner;

Fig. 2 is a perspective view of the heat Fig. 1, a portion of the receiving box at the to of the radiator being broken away;

Fig. 7 is a erspective view of a baflie eled to be positioned within the heating panel of the radiator.

Referring first to Fig. 1 which illustrates one environment where the improved heat radiator has utility, the heat radiator is generally indicated at H, the same being shown as positioned within an upright casing C from which the heated air flows into a conduit 10 which in turn delivers the air to the compartment or s ace to be heated. 11 indicates a blower or deliverin air into the casing G the blower being iven by? any ters t rough said conduit, the admission of air being controlled by a suitable damper or shutter generally indicated at 18.

As will resentl appear, the radiator is made up 0 a num r of hollow panels each having a top outlet 19 for the gases of combustion. Positionedion top of the radiator is a receiving chamber 20 wherefrom the gases of combustion pass into a conduit or flue 21 which delivers into a stack 22 leading to an appropriate point of discharge outside of thes ace or compartment to beheated. A water owl 23 is ositioned on top of the chamber 20, it being understood that the heated air will evaporate water from the bowl and thus impart humidity to the air 7 coming from the heat radiator.

The improved heat radiator comprises right and left hand members designated respectively by the letters R and L, both members being'of identical construction and being made of cast metal. Each member comprises a plurality of relatively wide and narrow and hollow panels generally indicated by reference characters R1 to R4, the corresponding panels for the left member L being designated by reference characters L1 to L4. The B group of pa.-=. extends upwardly inbroadside spaced relation from a base generally indicated at R5. The L group of panels extend in a similar manner from a base generally indicated at L5. The bases L5 and R5 are of such form and construction that each base forms one half of a combustion chamberK wherewith all of the panels are in communication as will be readily understood. The said bases are so formed as to ptrovide a sloping roof 30, for said chamber the. apex of the roof being the hne of -wel'ded to form a tight joint. noted that the group of panels rising from ipinder 31 between the two bases, L5 and R5. ach of said bases isproVided with a side flange 32 through-which are passed suitable securing means for making a tight joint between the flanges, or the flanges may be It Will be the base'f'R-5 extend laterally over the base L5, and that the panels'rising from the base L5 extend laterally-over the base R5. The two members L and R are assembled byinterdigitating the respective oups of panels thus permitting the bases secured along t eir marginal edges '31 and 32. The bases are provided with bottom flanges L6 and R6 to which the burner chamber 15 is secured. The burner chamber 15 is provided with downwardly extending side legs or supports 15 whereby to space the bottom of the chamber from the floor of the casing C wherein the heat radiator is placed. Air from the blower 11 may therefore flow beneath the bottom of said chamber thereby to keep it relatively cool. As shown in Figs. 1 and 2, the roof walls of the combustion chamber K may be provided with radiating fins 33. g

It is preferred to flow the burner gases in a circuitous path through each panel before passing from the panel outlet 19 thereof. 'To this end there is provided a baflie generally indicated at B, the baffle being inserted into the panel and being removable therefrom through. the top outlet19 in the panel. As

. shown in Fig. 7!, the bafile comprises upright legs 34 and 35 maintained in spaced parallel relation by webs 36 and 37 the leg 34 having an angular portion 38 which partially closes the panel outlet 19, said portion being provided at its terminal end with a downwardly extending lug 39 adapted to hook over the upstanding rim of the panel outlet 19. The leg 35 extends at an angle below the lower end of the leg 34 as indicated at 40, the terminal end of the extension to engaging with the end wall alof the panel. The legs of the bafie make a sufiiciently close fit with the broad side walls of the panel to cause the burner gases from the chamber K to flow in the circuitous path indicated by the arrows in Fig. 5, it being understood that the webs 36 and 37 are relatively thin to permit free passage of the burner gases.

By making the radiator in two separate similar sections L and B, it becomes a relatively simple matter to properly cast the sections as will be readily understood by those skilled in the art.

What I claim is:

1. In a heat radiator, the combination of similar right-and left members, each member comprising a plurality of relatively wide and narrow and hollow panels extending upwardly in spaced broadside relation from a common base, each panel having an outlet Lees,

5 and R5 to be atit's upperuend, the panels of one member 2. In a heat radiator as specified in claim 1, and means within said panels for causing the heating medium to travel in a circuitous path on its way to the panel outlet.

3. In a heat radiator as specified in claim 1, said basesbeing so formed as to form a sloping roof for said chamber.

4:. In a heat radiator as specified in claim 1, and a. receiving chamber extending across the tops of said panels.

5. In a heat radiator as specified in claim 1, the bottom of said chamber constituting a separate member.

6. A removable bafile element for a heat radiator having a relatively wide and narrow and hollow panel provided with an outlet at one end, comprising two legs maintained in spaced relation by connecting Webs, a portion of one leg adapted to partially close the panel outlet and the other portion of the same leg adapted to extend into the panel, the other leg extending angularly upwardly and forwardly from a point laterally below the lower end of the other depending leg and then directly upwardly to a'point short of the outlet closing portion of the other leg.

, In testimony whereof I affix my signature.
